Responsible for higher cognitive functions such as memory, emotions, impulse control, problem solving, social interaction, and motor function. Damage to the neurons or tissue of the frontal lobe can lead to personality changes, difficulty concentrating or planning, and impulsivity.
temporal lobe
The temporal lobe is largely responsible for creating and preserving both conscious and long-term memory. It plays a role in visual and sound processing and is crucial for both object recognition and language recognition.
Parietal lobe
It processes sensory information it receives from the outside world, mainly relating to touch, taste, and temperature.
Occipital lobe
The occipital lobe is the visual processing center of the mammalian brain containing most of the anatomical region of the visual cortex.
Blood Vessels of the Brain
Carotid Arteries
These vessels run along the front of the neck. There is
a right-sided carotid and a left-sided carotid artery. If a stroke happens in
this area, it can cause changes with speech, vision and sensation.
Vertebral Arteries
These vessels run along the back of your neck. There is a right-sided vertebral and a left-sided vertebral artery. The right and left vertebrals join to form one basilar artery. If a stroke happens in this area, it can cause changes with your level of awakeness, problems with musle movement and coordination, speech changes and vision problems.
Middle Cerebral Artery (MCA)
This vessel supplies blood to the middle part of
your brain. There is a right sided MCA and a left sided MCA. These blood vessels
are the most commonly affected in a stroke. If a stroke occurs in this area, you
may see:
Paralysis on one side of the body
Changes in sensation
Changes in sensation
Blindness (either on the left or right side)
Language problems, such as difficulty with forming words and sentences or
difficulty with understanding what others are saying.
These vessels supply blood to the back of the
brain. There is a right sided PCA and a left sided PCA. If a stroke occurs in this area, you may notice problems with vision.
